Abstract (en)
[origin: US4823274A] An injection molding machine wherein the values of variables for the current and several preceding molding cycles are displayed simultaneously, so as to perform process monitoring. Detection values of the variables in the current molding cycle are stored in a current value memory section of a memory (14). Every time a molding cycle ends, a CPU (11) transfers data from the current value memory section and past variable memory sections (which store the detection values of the respective variables of several preceding steps), to the past variable memory sections for the next preceding cycles. As a result the stored data of the memory sections is sequentially updated. The updated data and the current data are read out and displayed on a display unit (18).
